Does circumcision have any effect on my health?

Phimosis is a condition where the foreskin is too tight to be retracted behind the head of the penis (glans penis). They have different severity. The most severe kind will be one where the opening of the foreskin is so small that it may even cause problems during urination or cause pain during intercourse. Some may not be mild and can be retracted only when flaccid, but getting tight when erect. This may cause pain during intercourse and may also lead to Paraphimosis which is a medical emergency where the foreskin is stuck behind the head of the penis.

There is an incubation period from potential exposure to a STD from unprotected sex to when your body form antibodies to fight the STD. Why there is an incubation period for STD tests: STD tests look for the presence of these antibodies during testing, and if the STD tests are done before incubation period has ended, there may not be enough time for your body to develop enough antibodies for it to show up in testing, causing a false-negative result. Even after you have waited for the incubation period to end, you may not see signs or symptoms of the STD.
